|TITLE||Convergence of Adaptive Wavelet Methods for Goal-Oriented Error Estimation|
|AUTHORS||Wolfgang Dahmen, Angela Kunoth, Jürgen Vorloeper|
|ABSTRACT||We investigate adaptive wavelet methods which are goal-oriented in the sense that a functional of the solution of a linear elliptic PDE is computed up to arbitrary accuracy at possibly low computational cost measured in terms of degrees of freedom. In particular, we propose a scheme that can be shown to exhibit convergence to the target value without insisting on energy norm convergence of the primal solution. The theoretical findings are complemented by first numerical experiments.|
